Application filed. April it, 1818. Serial No. 229,%O l-.

To all whom it may concern:

Be it known that I, WALTER G. Pm, citizen of the United States, residingat Topeka, in the county of Shawnee and State of Kansas, have inventedcertain new and useful Improvements in Cream-Extractors, of which thefollowing is a specification, reifercnce being had therein to theaccompanying drawings;

This invention relates to a cream extractor, and has for its object thesimplification of means for extracting cream from a bottle and also toproduce a new and efiicient device for accomplishing the purpose justspecified.

.Vith this and other objects in view the invention consists of certainnovelconstructions, combinations and arrangement of parts as will behereinafter fully described and claimed.

in the drawings:

Figure 1 is a view in side elevation of a device constructed inaccordance with the present invention showing the same partly in theupper part of a milk bottle.

Fig. 2 is a view in side elevation, at right angles to the line uponwhich Fig. 1 is viewed.

Fig. 3 is an enlarged vertical sectional view of the device.

Fig. 1 is a top plan view of the device.

Fig. 5 is a perspective view of the plunger and the parts fixedlysecured thereto.

Fig. 6 is a bottom plan view of the device.

Fig. 7 is a horizontal sectional view taken. on the line 77, Fig. 3, andlooking in the direction of the arrows.

Referring to the drawings by numerals, 1 designates the body orcontainer, and 2, the top or cap thereof.

The body 1, has an annular horizontal flange 3, formed upon its lowerend consti tilting part or the bottom, and a central aperture 4;. Acrossthe aperture lis secured the guiding bar or plate 5, which bar 5 isprovided with a central aperture 6.

The cap or cover 2, is provided with a central opening 7, which openingor aperture 7 registers with the aperture 6, in the bar 5 at the bottomof the body or container 1, Fig. 3. Integral with the top 2, is acylindrical extension 8, and this extension 8 has its lower end attachedto a transverse strip 2 which strip 2 is a part of cap 2. The stripleaves sufiicient space on either side of rod 12, just above thehorizontal portions 10 of the grip device, is the follower-disk 1-3,which disk 13 is engaged by the lower end of the coil spring 14; thecoil spring 14: being mounted upon the upper or inner end of the plunger12 (Fig. 8), and the upper end of the coil spring 14 bears against thepeculiarly constructed thumb rest 15, hereinafter described.

The lower end of the plunger rod 12 is pointed as at 16, forfacilitating the positioning of the lower end in aperture 6; carriednear the lower end 16 is a valve disk 17, that normally closes theopening 1 in the bottom of the body 1.

My thumb rest comprises a curved body that is placed at an angle to thelongitudinal axis of the loops 11, and horizontal portion 10 (Figs. 1, 2and 4), so that when-the operator places two fingers in the loops 10,the thumb will restin a natural position against the thumb rest 15 ashas been discovered from actual experiment with a device constructed inaccordance with the present invention. Upon the thumb rest 15, and atone or its ends, is formed a curved, sharpened end portion 18, to beused in removing the caps from the milk bottles.

It is a fact that when milk is delivered in milk bottles the upper partofthe milk is cream, as a rule, and if a person desires to pour ed thecream then about one-hali the oured liquid is cream and half is milk.

ow, by using my improved device, only the cream need be extracted fromthe bottle, for by placing the fingers in loops 11, and the thumb inthumb rest 15, raising the plunger and its cooperate parts to theposition shown in dotted lines in Fig. 3, then inserting the device inthe milk bottle as shown in Fig. 1, only the cream need be permitted toenter the body or container 1, and upon all of the cream having enteredthe body 1, the

-ca mounted upon said body, said cap operator can release the loops 11and permit the valve disk 17, to be seated through the action of spring14, and then the device can be removed from the milk bottle and placedover cups or any suitable receptacle, and by raising the plunger and thevalve disk 17 the cream can be discharged at the will of the operator.

I wish it to be understood that I reserve the right to make minorchanges or alterations in the construction of my device as fairly fallwithin the scope of the appended.

claim.

- What I claim is:

In a device of the class described, the combination with a body providedwith a horizontal flange upon its lower end, and with an opening, a barprovided with a central aperture secured to said horizontal flange, a

rovi ed with a transverse strip exten ing across the same, said stripprovided with a central aperture registering with the aperture of saidbar, a; cylindrical extension integral with said strip, said extensionprovided with parallel slots, a thumb rest integral with the upper endof said cylindrical extension, a plunger rod normally positioned in theapertures of said strip and said bar, a valve disk secured to theplunger near its lower end, said disk resting against the inner face ofsaid horizontal flange, the lower end of said plunger being sharpenedfor the insertion thereof in the aperture of said bar, a finger devicesecured to said plunger, said finger device comprising a horizontalportion extending through the parallel slots of said cylindricalextension, said horizontal portion provided at its ends with integralloops, a follower disksecured to the plunger above the horizontalportion of said finger device, and a coil spring on the inner end ofsaid plunger, and engaging, at its inner end, the follower disk, andengaging at its outer end, the thumb rest.

In testimony whereof I hereunto aflix my signature.
